Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490484, here are decompositions:

71 + 2147490413 = 2147490484
431 + 2147490053 = 2147490484
641 + 2147489843 = 2147490484
941 + 2147489543 = 2147490484
947 + 2147489537 = 2147490484
1061 + 2147489423 = 2147490484
1187 + 2147489297 = 2147490484
1193 + 2147489291 = 2147490484

Showing the first eight; more decompositions exist.

IPv4 address
